Google Israel turned out the lights and flipped their white background color to black for שעת כדור הארץ (aka Earth Hour). What is ironic is that we reported in the past that Google argued that black uses more energy that white. (Although they participated in Lights Out San Francisco last October as a symbolic turning out the lights and noted then it was an effort to raise awareness about energy conservation — not that turning the home black conserved energy itself.)
In any event, Google will likely close the shades on Google.com on March 29th at 8pm, the time of Earth Hour in America. Don’t forget to shut off your lights between 8pm and 9pm on Saturday!
